"I'm pleased that we can now sign this agreement with unions and employers, to extend the Care and Support Workers [Pay Equity] Settlement Act to include these important workers.
"Ensuring our mental health and addiction workers are paid what they deserve will help deliver a robust workforce."
The settlement extension will be implemented over five years and funded through an increase to the health budget.
The Care and Support Workers (Pay Equity) Settlement Act increased the pay rates of 55,000 care and support workers in aged and disability residential care, and home and community support services.
It was the case of rest home worker Kristine Bartlett that was the catalyst for the previous National government's $2 billion pay equity settlement.
"These workers were unfairly left out of the equal pay care and support settlement by the National government, and we're thrilled to see this wrong righted today," PSA assistant national secretary Kerry Davies said.
"We're really happy the Government has honoured its election commitment to extend the care and support settlement to mental health and addiction support workers," E tū assistant national secretary John Ryall said.
